Definitions

  • the present invention relates to a mouthpiece which can be exclusively used by a specified user and which can protect the jaw bones, teeth, and oral cavities from external force in view of moldability, flexibility, and elasticity.
  • the present invention further relates to a method of producing such a mouthpiece in a simple manner.
  • a mouthpiece comprising an ethylene-vinyl acetate copolymer having a vinyl acetate content of from 12 to 33 wt%.
  • the mouthpiece according to the present invention is produced by using an ethylene-vinyl acetate copolymer. Accordingly, the softening point of the ethylene-vinyl acetate copolymer can be adjusted by changing the content of the vinyl acetate, so that it is possible to provide a satisfactory mouthpiece improved in moldability and provided with flexibility and elasticity.
  • the vinyl acetate is contained for adjusting moldability and flexibility of the ethylene-vinyl acetate copolymer. For example, a larger content of vinyl acetate in the copolymer provides a smaller rigidity modulus, a higher flexibility, a lower heat deformation temperature, and the better moldability at a low temperature. In view of the above, it is preferred that the content of the vinyl acetate is from 28 to 33 wt%.
